Fig. 2 is a fragmentary enla geclgentml' longitudinal sectionalwiewpfthq ,s pindle Fig. 3 is a view'si h a i tolFig. 2, aiseCti n i" i l r therewith of the inner surface of the shield" as shownin Fig.2. The end portion 11 of the opening 10 of the shield lies adjacent the conicalsurface of the spindle roviding an annular space 14: slightly larger at lts upper end for receiving the base of a wlnding cop.- The walls ,of the-shield extend slightly beyond the knife edges to protect the same from injury, and to prevent it from injuring the operator. g

I The spindle is adapted for. receiving the winding core or cop 15 which. is preferably a conicaltube corresponding to the conical formation of the-spindle, and may be constructed of layers of fibrous material such as paper, wound one over another and cemented together to "form walls sufficiently stiff and rigic'l to support the convolutions of silk or other threads to be wound thereon. One of the purposes of the spindle C011- struction herein'described is to form automatically slits 16 in the end of a cop as the a same is placed inposition on the spindle as shown in Fig. 1, the purpose of such slits being'to receive'an'd hold the loose end of aball of thread wound on the cop. It will be obvious that this function is accomplished as the lower end of the cop is forced to seating position into the annular space 10 against the-cutting edges 7 and 7 of the knife disposed therein. The bottomof this space maybe utilized to limit the entry of the cop and consequently the depth of the slits, orthe depth may be regulated by contact of the inner surface of the cop against the conical surface ofthe spindle. It will also be seen that the lower end of the cop is protected by the shield, and that the spaced portions of the knifeblade penetrate and grip the lower end of the cop at its diametrically opposed walls to prevent rotation thereof on the spindle, while accidental contact with the knife edge on the part of the operator is effectually guarded against.

As many changes could be made in the above construction and many apparently widely different embodiments of this inventionpould be made withoutv departing from the scope thereof, it is intended that all vmatter contained in the above description orshown in the accompanying drawings shall be interpreted as illustrativeand not in a limiting sense. g

It is also to be understoodthat the language used in the following claims is in The blade may be supported vention which, as a matter'of language,

might be said to fall therebetween.

Having described my invention what I claim as new and desire to secure by Letters Patent, is

1. A spindle for use in Winding textiles adapted to receive a cop, and means associated with said spindle for preparing said cop for gripping the end of a thread Wound thereon. I

2. A spindle for use in winding textiles provided with a shield for receiving the end of a cop, and means associated with said spindle for forming a. slit in said cop for gripping the end of a thread wound thereon.

3. A spindle for use'in winding textiles adapted to receive a cop, and a cutting olevice secured to said spindle for forming a slit in said cop thread wound thereon.

4. A spindle for use inflwinding textiles provided with a shield for receiving the end of a cop, and a cutting blade with an outwardly directed edge secured to said spindle for automatically slitting said cop when placed on 'said spindle thereby providing means to secure the loose end of a thread wound thereon. i

means for securing the loose end of the thread. 7

6 A vspindle for use in winding textiles adapted to receive a cop, a slot formed transfor gripping the endof a 5."A spindle'for use in winding textiles versely in said spindle, acuttingblade disposed in said slot, and a shield on dleencompassing said blade. I

7. A spindle'having a shield secured near one extremity thereof, said shield having a portion spaced from said spindle to pro vide a receiving, recess for the end of a cop, and means disposed in said recess for preparing said cop for gripping the loo'se end'of a thread wound'ther'eon. i

8. In a device of the character described. in combination, a spindle having a conical said spin surface adapted to"v receive a conical cop, a;

shield associated withsaid spindle overlapping said conical surface to provide an annula'r'space, and a cutting'device disposed in said .annular space. -'In testimony whereof I afiix my signature, in the presenceof-two witnesses.
